Reloading for precision

[Bustercluck]

A couple topics if anyone wants to share.

What’s your reloading technique for f-class, benchrest or other shot to shot consistency type shooting?

What does improving each step net for accuracy improvements? Or what’s the most important steps(in order) to improve your technique?

Every time I think I’m gtting better and I’ve only got a few more things to buy, I suddenly find something else on the internet to improve some other part of my process. I’m betting the established f-class shooters have $10k (or more) worth of reloading equipment.

I use the best components I can buy that work in my rifles for ultimate accuracy.
I weigh on a beam scale if i want the ultimate accuracyy load for the longer distances. It's slower than an electronic measure and scale but it works .I practise shooting in the worst conditions I can, because TR and Fclass are games of score not group size.
If I can make good wind call in lousy conditions , shooting a good score in good conditions is easier .

It's not the equipment that you need, it's the time and labor to prep everything to be loaded, the powder and seating the bullets is the easy part.

sorting bullets base to ogive, weight/volume sorting brass, uniforming primer pockets, flash holes, skim turning necks, chamfer, deburr.......

bullet seating tests, tweaking powder load, fine tuning bullet seating, playing with neck tension, neck lubes, neck clearance in the chamber

lapua and berger take alot of the above out, but not all of it

I’ve never bothered weight sorting brass, or doing much brass prep at the new stage. I do turn most of my necks as long as I have the right sized mandrel and stuff here.

As far as sizing I’m trying to full length size with a bushing die and the redding competition shell holders to bump the shoulder back .001” or so, or at least until there’s no resistance closing the bolt on a loaded round. I bought a bunch of mandrels .001” smaller than bullet size over the winter, but haven’t had a chance to try them out yet.

Anneal every firing with a 2 torch annealer.

Trimming to length every time and obviously chamfer. I’ll probably buy one of those rcbs/Henderson trimmers as soon as they’re available in canada. This is one step that takes too long for me and that rcbs trimmer will probably do a better job than I do.

Cleaning is something I bounce all over the place on. Lately I went back to the walnut tumbler. Sometimes I just wash them by hand to get the lube off.

Weighing powder to within a granule.

The next tool on my list is going to be an arbor press and inline seating dies. I don’t think I’ll bother with a force pack, but who knows, maybe I’ll grab one that can be upgraded later.

The thing I was wondering about today is if I should get a precision primer seater? It’s not a huge investment, but I’m really struggling with how much something like that is going to improve things down range.

I’ve been measuring bullets too. From
what I understand most guys are only length sorting these days and not weight sorting. Maybe if I learn to shoot good enough to kotice than I’ll start doing that too.

Do you fill your cases with water over a scale to compare volume? After you weight sort them? Is this something you do after firing them in your chamber? Or new?

I totally agree on the time factor. I’ve been trying to get tools that make everything faster and still maintain quality. And I bought lots of brass for everything I shoot lots so I always have backups, but I still seem to runout. Lol

I don't shoot for precision... I do however load for it... I think...
For me it took about 30 years to come to terms with shooting bambi... even thought I grew up ranching and understood where our food comes from.. My respect for critters may be a fundamental flaw but it lead to my need to produce accurate ammunition for my needs. Store bought ammo was wildly inconsistent regardless of my skill. So I dove into the world of reloading..... and have been learning every day... sometimes it's a tiny detail but they all add up. My next process was going to be weight sorting... So I'm curious what others think as well. Great question. Thank you. Cheers

I feel like the most important thing is barrel quality and component quality. If you are running junk then reloading technique will be like trying to make a racehorse out of a donkey, so to speak.

But assuming you have that part covered this is where I am at:

1) Use quality brass (Lapua for me but there are other options out there too) and keep it in a batch (ie fired same amount of times and treated the same way each time). This is an easy win.

2) I anneal after every firing.

3) Size just enough that the case will chamber easily (some measurement required)

4) I size with no expander ball (deprimed already as a first step before cleaning) and then use a mandrel to size the necks. For me this was one of the bigger improvements. Ultimate Reloader did a video this week where he used an automated AMP press to quantify the difference between the two different methods and it seemed pretty convincing.

5) The more consistent / accurate your powder throws the more consistent your ammo should be. I wont get into what is best as it often stirs up emotion but the more accurate the better IMO.

6) Test to see what your rifle likes for jump. Some are more fussy than others. I did a test just yesterday and 20 thou was one ragged hole, 40 thou was noticeably worse (every other variable was identical). Note, Berger hybrids seem pretty much impervious to jump. If there is too much or too little I haven't noticed it with them.

Thats all I can think of for now. To sum it up easily, consistency, consistency, consistency.
